ANYthing on an empty stomach is bad, at least for me... had the "heebee jeebies" from a Perdomo La Tradicion Champagne! Of course, inhaling didn't help, either... Live and learn, live and learn...oh yeah, LFD's on empty stomach, yumm.
I'd say the strongest body I've had is the Joya de Nicaragua Antano, Camacho Coyolar, or Partagas Black Krystal.
The strongest flavor, though, is a toss up between four: the Cohiba XV, St Luis Rey serie G mad, Felipe Dominicana (old/ pre-release blend) torp , and the Tatuaje reserva J21.
Just my 2 cents,
